HydroxyPropyl Methylcellulose (HPMC) CAS: 9004-65-3 Chaw Tsim Khoom Siv

Hydroxypropyl Methyl Cellulose (HPMC) yog cov polymers uas yaj tau hauv dej uas tau los ntawm cellulose. Feem ntau lawv siv ua cov khoom ua kom tuab, cov khoom khi, cov khoom ua zaj duab xis, thiab cov neeg sawv cev khaws dej. Lawv kuj ua haujlwm ua cov khoom pab rau kev ncua, cov tshuaj surfactants, cov roj nplua nyeem, cov colloids tiv thaiv, thiab cov emulsifiers. Tsis tas li ntawd, cov tshuaj ntawm cov polymers no ua rau cov gel kub. Hydroxypropyl methyl cellulose siv ua cov roj nplua nyeem qhov muag, cov emulsifier thiab cov neeg sawv cev ua kom tuab thiab ncua. Nws siv dav ua cov khoom siv hauv cov tshuaj. Nws ua haujlwm ua cov khoom noj khoom haus ntxiv. Nws cov tee qhov muag hu ua cov kua muag dag, uas siv los txo qhov muag qhuav thiab mob. Nws pom cov ntawv thov hauv ntau qhov chaw ua emulsifier, zaj duab xis tsim, cov colloid tiv thaiv, cov stabilizer, cov neeg sawv cev ncua, lossis cov khoom ua kom tuab hauv cov khoom noj. Cov khoom pab tshuaj (cov neeg sawv cev ncua; cov tshuaj ntsiav; demulcent; tus neeg sawv cev nce viscosity); tus neeg nqa dej hydrophilic hauv cov txheej txheem xa tshuaj. Hauv cov nplaum, cov emulsions asphalt, cov khoom sib xyaw caulking, cov vuas pobzeb, cov yas sib tov, cov cements, cov xim.
